Ashleigh • Engaged to my best friend and soldier. We have a 5 year old son, and currently ttc our second ❤️
I'm going on day 11 of having EWCM. Which is out of the norm for me. I don't use opks as we currently don't have a bunch of extra money to buy test kits. I went to my obgyn and was told to bd every other day as we've been doing and to just use EWCM as an indicator of when I'm in my fertile window. I also had cramps two out of these days, so those two days we bd as well. I know my body pretty well and know when my egg is releasing from the cramps. But why the EWCM this long? Does anyone know or expierence this?
